A philosophy can and must be worked out with the greatest rigour and discipline in the details, but can ultimately be founded on nothing but faith: and this is the reason, I suspect, why the novelties in philosophy are only in elaboration, and never in fundamentals.
See skulking Truth to her old cavern fled, Mountains of Casuistry heap'd o'er her head! Philosophy, that lean'd on Heav'n before, Shrinks to her second cause, and is no more. Physic of Metaphysic begs defence, And Metaphysic calls for aid on Sense! See Mystery to Mathematics fly!
The army ages men sooner than the law and philosophy; it exposes them more freely to germs, which undermine and destroy, and it shelters them more completely from thought, which stimulates and preserves.
Even today many educated people think that the victory of Christianity over Greek philosophy is a proof of the superior truth of the former - although in this case it was only the coarser and more violent that conquered the more spiritual and delicate. So far as superior truth is concerned, it is enough to observe that the awakening sciences have allied themselves point by point with the philosophy of Epicurus, but point by point rejected Christianity.
Atheism leaves a man to sense, to philosophy, to natural piety, to laws, to reputation, all which may be guides to an outward moral virtue, though religion were not; but superstition dismounts all these, and erects an absolute monarchy in the minds of men.
Philosophers are not honest enough in their work, although they make a lot of virtuous noise when the problem of truthfulness is touched even remotely. They all pose as if they had discovered and reached their real opinions through the self-development of a cold, pure, divinely unconcerned dialectic...; while at bottom it is an assumption, a hunch, indeed a kind of "inspiration" most often a desire of the heart that has been filtered and made abstract that they defend with reasons they have sought after the fact.
In Hindu philosophy the whole creation is regarded as the Vishnu Lila, the play of Vishnu. Lila means dance or play. Also in Hindu philosophy, they call the world illusion; and in Latin the root of the word illusion is ludere, to play.
